How useful would Japanese escorts be in the Battle of the Atlantic, and could Japan equip them with Asdic?
Short answerThey would be useful, and Britain could supply or retrofit Asdic so the ships could join Allied anti-submarine operations.
NotesJapanese escorts could make a useful contribution to the Battle of the Atlantic. Japan could build Asdic if Britain supplied the necessary equipment or knowledge. Existing ships could also be refitted with it. The alliance would therefore offer a way to adapt available hulls for Allied anti-submarine operations.
